CARRBAGE-V-ELEASE DEVICE FOR` TYPE-WRITERS..

Application nga Jua. 8,1904.

To a/ZZ whom it may concern:

Be it known that I, EMMET M. INGERsoLL, a citizenof the United States,and a resident of Woodstock, in the county ofMcHenry and State ofIllinois; have invented certain new andl useful Im frovementsf inCarriage-Release Devices or e-Writers; and I do hereby declareytha'tlllihe following is a' full,

clear, and exact description thereof, reference being had t6 theaccompanying draw-- ings, and to thelettersfof reference marked thereon,which form a part of this specifica- Ils tion.

This invention relates to an improved device forreleasing the carriageof a type-writing` machine Jfrom its letter-spacin mechanism, wherebythe -carria e may be moved freely in either direction om end to end ofits travel, thereby facilitating the insertion of characters on analready-printed line or for other purpose.`

My lmprovements are herein shown asapplied to an Oliverf type-writingmachine,

wherein endwise Imovement'of the carriage under the action of itsactuating-spring 'to produce the letter spacing is effected through lthemedium of an escapement mechanism Yembracing a rotative pmionwhich isyieldingly held in intermeslnng relation with a rack-bar onthecarriage-frame, and said carriage is disengaged from the escapementmechanism by a releasebar adapted to force `said pinion out of mesh withthe rack-bar.

My improvements may,however, be applied to other type-writing machineshaving the same general construction -of parts for effect-J ingletter-spacing.v

Fig. 3 is a cross-section of the carriage,taken on line 3 3 of Figs. `1 and 2, showing also parts of themachine-frame and the letter-spacing mechanism.- Fig/iis a fragmentarysection-taken on line 4 4 of Fig. 8. Fig. 5 is a sectional view of therackbar and the releasing device, taken on line 5 5 of Fig. 2.

Said carriage embraces end plates B2 B2, which support the platen andthe `paper guiding an apressing devices,I and front and rear lon tu malmembers B3 B, affixed at their en s to said Aend lates. The carriage issupported on the shlft-frame through the medium of rollers b b', whichtravel on horizontal parallel rails A A2, extending-longitudinally ofthe shift-frame.' The letter-spacing mechanism for the carriage embracesa rack-bar B5, herein shown as formed integrall with the frontlongitudinal member B3 of the carriage-frame, and an intermittingl-rotative driving-pinion A3,'mounted on t e'up per end of an upright"shaft A, which turns 1n suitable bearings in the shift-frame. As hereinshown, the upper end of the shaftis rotatively mounted 1n a block a,which slides [toward andfrom the rack-bar in a slot a',

formed in; the shift-frame, and is yieldingly thrown toward therack-baribyaspring a2,

-which isapplied to act on said block,- lFigz 4.

The lwer end of the shaft A-i has a bearing in a horizontalforwardly-extending arm A5 on the shift-frame, and the bearing-socket insaid arm is made of such size as to permit theV upper-end of the shaftto swing rior United States Letters Patent to' -homas Oliver, No.599,863, dated March 1, 1898. The bar-is provided near its ends withoblique parallel slots c, through which .eX- tend headed holding'andguide studs c', that are secured in and rise from the rack-bar.

The said releasebar is moved obliquely in a `horizontal plane by meansof an endwisesliding actuating-rod C', loosely connected at its innerend with one end of the releasebar and provided at its outer end with aknob or button c2.

The actuating-rod extends through and' IOO has sliding engagement withthe end plate B2 p LII ci the carriage. When pressure on theactuating-rod is released, the release-bar is restored to its normalposition, away from the pinion A3, by means of a retracting-spring C2,herein shown as having' the form of a spiral contractile spring, whichis attached at one these parts of thev @liver type-Writing ina-y -claineThe paper guiding and pressing devices associated With the platen E areof the` usual construction found in the @liver typeting machines andconstitute no part of present'inve: ion.

The outer end d of the .lever outside its pivotextends through an opening in the end plate oi the carriage and islocated below and slightly. in iront oi the adjacent turning-knol; B7 onthe platen-shaft. The inner end of the lever is'adapted to bear againstthe inner Ynace ofthe vertical ange c3 ci the release-bar, as clearlyshown in Figs. 2, 3, andv 5, the release-har being adapted I to freelyslide endWise relatively to the lever.

- pressure y through the medium of the lever D has the Tifhentheouterend of said lever is pressed rearwardly, therefore, the inner endthereof is carried forwardly against and transmits a '.orvvardhorizontal ino vement to the releasepar.

eing imposition to be, engaged by the thumb of the hand which grasps theplaten-- turning knob. The carriage `el? a machine thus equipped may loereadily released by' either hand, and inasmuch as the tripping de vicesare carried by the carriage and located .in position to be moved by thehand which grasps the platen-turning knob and controls the endvvisemovement of the carriage they are always in position for immediate .andconvenient operation by either hand.
